Assumptions and information: There is a one-family dwelling unit that you need to calculate feeder load for. Exterior dimensions of the unit for load purposes: 25ft x 30ft System nominal voltage for lighting and small appliances is 120V. • There are total of 20 outlets for small appliances, each for 180 VA load. One laundry circuit is installed. Fixed appliances in this unit: O One water heater with three 4000-watt elements and requires 240 V electrical connection. O One 20 Amps dish washer (voltage = 120V) 0 One 5 Amps food disposer with wall key (voltage = 120V) Electric dryer has nominal load of 4550 VA on its nameplate and requires 240 V electrical connection. One electric range/stove is used in this unit's kitchen, with nameplate rating of 18.5 KW. ● ● ● ● Questions: 1. Calculate the general lighting load for this dwelling unit, assuming 3 VA/sqft. 2. How many 20A circuits are required for the load in question 1 (exact number)? 3. Considering 1500 VA load per each circuits for small appliances, calculate the total load for small appliances. 4. If laundry circuit counts as 1500 VA, calculate "feeder load" for lighting, small appliances and laundry, using correct demand factors (table 220.42.) 5. Calculate the feeder load for all Fixed Appliances of this unit (all connected to one feeder). Use the correct demand factor. 6. Calculate the load for this unit's electric range, using instructions from Table 220.55 Notes. 7. Calculate total service load for this unit.
